Perth star Shawn Redhage hit the game-winner for the second time in as many weeks, lifting the Wildcats to a comeback 75-71 NBL win over the Melbourne Tigers on Sunday.

The Tigers were celebrating the 20th anniversary of their first NBL title but the Wildcats gatecrashed the party, recovering from an early 15-point deficit to extend their unbeaten start to the season.

The Wildcats (3-0) top the ladder after two rounds, with Cairns (2-0) the only other team yet to taste defeat.

Redhage finished Sunday's match with 25 points at 58 per cent.

His mid-range jump shot with 10 seconds remaining came a week after he also scored the match-winner against Adelaide.

Star import James Ennis (21 points) also played a key role in Perth's win.
